Is this it?? Were there enough fan reactions that finally woke the team up and decided to create a long awaited sequel??
While reading the Dissidia Wiki, I came across this,
"Tetsuya Nomura has stated that there are no immediate plans for a sequel to Dissidia, although it was discussed. However, depending on fan requests and the success of the first game, this may change in the future. According to an interview between Takashi Arakawa and Yoshinori Kitase (director, writer, and producer) with a German gaming site, Kitase stated that a sequel would be ‘very interesting’, and might even include Kingdom Hearts characters, although it would still have to be discussed with Disney. Nomura has said that a potential sequel would include Kain Highwind, Gilgamesh and Sazh Katzroy representing Final Fantasy XIII, but would not include Kingdom Hearts characters.

- In a recent interview, Nomura has stated that he will "do his best" to create a sequel to Dissidia due to fan reactions."

I was disappointed too when they said Lightning was DLC but someone dawned on me that Dissidia isn't really created with DLC in mind. And I think Nomura's high up enough in the company. He worked his way up from monster design to character to finally directing one of the best action/rpg to date [Kingdom Hearts]. Oh and he's taking care of VS XIII too so...I think he's in a pretty good shape with SE
